SPECIFICATION forming rt of Letters Patent No. 723,896, dated March 31,1903.

Application filed Angpst 16, 1902. Serial No. 119,960. ,(IIo model.)

To all whom it may concern: V 1 Be it known that I, FRANCIS B. MOORE,residing at Metamora, in the county of-Woodford and State of Illinois,have invented cer- 5 tain new'and nsefulImprovemen'tsin Ground- Rollers,of which the following is a specification.

- My invention relates to thatclass of gron ndrollers having a rollprovided with a cylindrical body portion and a spiral flange or flangesencircling such body portion and protruding radially therefrom andhaving end' trunnions upon which such roll is rotatably mounted.

It relates, further and particularly, to that class of ground rollershaving a suitable frame, a cylindrical roll rotatably mounted in suchframe, provided with end trunnions and an encircling spiral flange, anda cylindrical roll provided with a smooth peripheral surface and mountedrotatably in suchframe adjacent to and in=sliding contact with thespiral flanges of the flanged roll, whereby the flanged rollis adaptedto indent, loosen, and level the surface of the groundto be operatedupon and at the same time scrape the accumulations of dirt from thesurface of the smooth roll.

It relates, further and finally, to groundrollers provided with asuitable frame having roller-bearings therein, a cylindricalspirallyflanged roll provided with end trunnions and rotatably mountedin hearings in such frame, and a cylindrical smooth-surfaced rollrotatably mounted in such frame adjacent to and in sliding contact withthe spiral flanges of the flanged roll, whereby the flanged roll isadapted to indent, loosen, and level the surface of the ground to beoperated .upon and at the same time scrape from the peripheral surfaceof the smooth roll such dirtas may accumulate thereon, and whereby theweight of either roll may be substantially transferred to the other, ascircumstances and the varying condition of the ground may require.

My invention consists in the features, combinations, and details ofconstruction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is 50 a plan view of a rollerconstructed in accordance with my improvements, and Fig. 2 is a View incross-sectional elevation taken on line 20f Fig. 1.

In constructing a groundq'oller in'accordance with my improvements Iprovide asuitable frame portion a, in which is mounted a roll I),haviug, preferably, integral protruding spiral flanges c, encircling theouter peripheny thereof and extending outward radially beyond themainbody portion of'such 6o cylinder. This roll is also provided with endtrunnions d, rotatably mounted in-bearings e of the frame, whichtrunnions are preferably integral-with the end portionsfof the roller.

The spiral flanges of this roll are preferably V-shaped and arranged ata distance from each other corresponding substantially to the depth ofsuch flanges, although. these proportions may be changed as desiredwithout departing from the spirit of my invention. second roll h,havi-nga smooth peripheral surface tl, is niounted rotatably in theframe adjacent to theflanged roll, so that its outer peripheral surfaceis in sliding contact with the spiral flanges of the flanged roll. Thissecond roll is also provided with trunnions cl, corresponding to thoseof the flanged roll and mounted in bearings e in the frame, similar tothose in which the flanged 'roll is mounted.

Both of the rolls above described are pref- 8o er ably of cast metal andmay be made hollow and of any desired size and proportions. It will bereadily apparent, however, to those skilled in the art thatby thisarrangement the weight of either roll may, when desired, be readilytransferred to the other'when the conditions of the ground requireisuchadditional weight upon either the flanged or the smooth roll. Eitherroll may tliusbecome as effective for all practical purposes as a singleroll of twice its weight. It will also be readily seen that by thisarrangement the flanged roll is adapted to indent, out, and loosen theground and smooth-it to a certain extent, removing the more prominentprotnloeran'ces, and at the same time the spiral flanges being insliding contact with'the smooth roll will scrape therefrom all dirtwhich may accumulate thereon, thus leaving the smoothing-rollconstantlyin condition to efficiently perform [00 its function ofcompressing and smoothing the ground. A removable sliding finger Zcleans the flanged roll.

In order to enable the weightof either roller to be readily transferredto the other and the apparatus operated in an efficient manner, a handleis provided and connected to the frame portion by means of a socket orbrace is, which may beriveted or bolted to the frame in any ordinary andwell-known manner.

An apparatus is thus provided by means of which when the conditions ofthe ground require substantially equal weight in both rollers the weightmay be readily equalized. When a certain portion of the ground requiresa greater proportion of loosening or stirring, the weight. of the smoothroll may be transferred to the flanged roll, and when it requires morecompactness the weight of the flanged roll may be readily transferred tothe smoothing-roll in either case by simply raising the roll which isleast required.

I claim-- 1. In an apparatus of the class described, the combination ofa cast-metal roll'consisting of a cylindrical main body portion havingintegral spiral flanges extendingoutward radially therefrom, integralend portions provided with trunnions arranged centrally thereof, and aframe in which such roll is 1'0- tatably mounted, and a finger slidablymounted in the frame and extending between the spirals of the flange,substantially as described.

2. In an apparatus of the class described, the combination of a metallicroll having a cylindrical main body portion provided with spiral flangesextending outward radially beyou'd the peripheral surface of such maincylindrical portion and provided with end trunnions, a frame in whichsuch roll is rotatably mounted, and a roll provided with a cylindricalmain body portion having a smooth outer peripheral surface in slidingcontact with the flanges of the flanged roll and rotatably mounted insuch frame, substantially as described.

3. In an apparatus of the class described, the combination of a rollprovided with a cylindrical main body portion having integral spiralflanges extending outward from such main body portion, end trunnions forsuch roll, a frame in which the roll is rotatably mounted, a. rollprovided with a cylindrical main body portion having a smooth peripheralsurface arranged in sliding contact with the spiral flanges of theflanged roll and rotatably mounted in the frame adjacent to such flangedroll, and a handle rigidly connected with such frame, substantially asdescribed.

4. In an apparatus of the class described, the combination of a frame, aroll rotatably mounted in such frame provided with a cylindrical mainbody portion having integral V-shaped spiral flanges encircling theouter peripheral surface thereof, integral end portions for such rollprovided with integral trunnions, and a roll provided with a cylindricalmain body portion having a. smooth outer peripheral surface rotatablymounted in such frame in operative engagement with the flanged roll,substantially as described.
